GS-R400 Family
20W TO 140W STEP-DOWN
SWITCHING REGULATOR FAMILY
June 1994
1/5
FEATURES
MTBF in excess of 200,000 hours
4A max output current
46V max input voltage
4V max drop-out voltage
Soft start
Remote logic inhibit/enable

DESCRIPTION
The GS-R400 series is a versatile family of high
current, high voltage step-down switching voltage
regulators.
The integral heatsink allows a large power handling
capability and it provides also an effective shielding
to minimize EMI.
